-

Imprint: L612
Drug Class: H1 receptor antagonist (non-drowsy antihistamine)

What Does the L612 Pill Treat?
L612 (Loratadine 10 mg) provides fast, long-lasting relief for the following:
Condition | Effective? |
---|---|
Seasonal allergies (hay fever) | ✅ Yes |
Indoor allergies (dust, mold) | ✅ Yes |
Pet dander allergies | ✅ Yes |
Skin allergies (hives) | ✅ Yes |

How L612 Works in the Body
Loratadine works by blocking histamine H1 receptors — preventing the release of histamine, the chemical that causes:
-
Sneezing
-
Runny nose
-
Watery eyes
-
Itchy skin
-
Post-nasal drip
Second-generation antihistamines like Loratadine act only on peripheral receptors, which means:
-
✅ Less drowsiness
-
✅ Longer-lasting effect (up to 24 hours)
-
✅ Safer for daily use
